Windows PCs and laptops require a dedicated fan to support heat dissipation. The fan helps keep the hardware cool and ensures it doesn’t overheat in any intensive work or task. During peak performance ...

This post is a quick sequel of my previous article jam-packed with my personal experiences and observations while I was fiddling with standard 4-wire PC cooling fans. Today I will be talking about the ...

The fan runs constantly in many PCs, which may not even be necessary. A simple controller circuit can regulate the fan speed according to demand. This not only saves energy, it also reduces irritation ...

As anyone who has worked with their laptop on their lap knows, after a while your computer gets hot. The greater the demands you place on your notebook, such as running multiple programs or using ...

Most newer computer motherboards are equipped with pulse-width modulation controllers that can be used to control the revolutions per minute of the internal cooling fans. Whether one of your business ...

If your computer's running a little loud for your tastes, it's probably because your fans are running at full speed—even if they don't need to be. Here are a few ways to manage your fan's speed so ...

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

AUTO /MANUAL manual mode automatic mode switch. Big LCD screen to display the temperature, fan speed, alarm temperature, hard disk state, to constantly know the the working condition. Smart adjust the ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

Another common mistake is omitting the rear fan. This fan is one of the most important in the system because it sits in the ...

CPU_FAN and CPU_OPT are entirely different and serve distinct purposes in the context of a computer cooling system. CPU_FAN or CPU Fan Header is the primary 4-pin fan header on a motherboard, and it ...
